Title: Electrophotographic toner
Inventor: ONO JUNICHI
IPC: G03G9/087
Filed: 1986-02-03
Abstract: PURPOSE:To improve print resisting power by using at least one kind of compd. selected from an epoxy resin or modified epoxy resin and compd. contg. a block isocyanate as essential components. CONSTITUTION:The block isocyanate as a curing accelerator for the epoxy resin or amine-modified epoxy resin does not exhibit reactivity as a -NCO group is masked at an ordinary temp. and temp. conditions in the process for toner formation. The blocking agent dissociates and reacts with the -OH group of the above-mentioned epoxy resin or amine-modified epoxy resin when the temp. increases. The block isocyanate is added at 1-20pts. per 100pts. epoxy resin or amine-modified epoxy resin, by which a resin having high adhesive powder to special silicone rubber, etc., having ink repellency is obtd. The adhesive power or print resisting power to a waterless lithographic plate is thereby improved.

Title: Radar device
Inventor: HARASAWA YASUHIRO
IPC: G01S13/89
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To make improvable the quality of displayed image by calculating a frequency error generated due to measurement error of the speed of a radar device itself using an output data of an FFT operator and shifting the frequency of the output data by a value corresponding to the error. SOLUTION: Processed results of an FFT operator are transferred to a peak frequency detection means 21a and a frequency indicating the peak intensity of the output data is detected. In an antenna beam directional angle memory 23a, the directional azimuth of the antenna beam is contained one by one. With a frequency shift means 22a, a frequency fb corresponding to the central azimuth of the beam forwarded from the antenna beam directional angle memory 23a is calculated. By comparing the frequency fb and the frequency fp forwarded from the peak frequency detection means 21a, processed data are shifted on a frequency axis so that they coincide with each other. In short, the frequency error Δf is obtained with Δf=fb-fp so that the contained data series can be shifted by the frequency corresponding to |Δf|.

Title: Base structure of bipolar transistor
Inventor: KAKINUMA HIROAKI
IPC: H01L21/331
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain the low-resistance base layer of a bipolar transistor in spite of its thin base layer, by making its base structure a modulated doping structure. SOLUTION: The base structure of a bipolar transistor is made to be the one wherein an undoped i-type GaAs layer 12-2 is sandwiched from an upper and a lower sides by heavily doped layers 12-1 with such P-type dopants as Zn, Cd, C (each of their concentrations is about 1×10<19> -5×10<10> cm<-3> ). Therefore, the holes of the heavily doped layers 12-1 with the P-type dopants are moved by diffusions to the undoped i-type GaAs layer 12-2 to make this layer 12-2 into a P-type layer. But, since the undoped i-type GaAs layer 12-2 has no ionized acceptor, the holes can transit the layer 12-2 to be scattered scarcely. Thereby, since the equivalent mobility of the base layer increases, the base resistance can be reduced to enable the high-speed operation of the transistor.

CONSTITUTION:The rejuvenation time of a trap 53 catching and collecting particulates during exhaust is decided by means of a means 57 by comparing a trap front and rear pressure difference detected by means of a sensor 56 with a trap front and rear pressure difference at the time of catching and collection limitation set by means of a means 55. As a result, when it is decided that it is a rejuvenation time, a device 54 which makes the temperature of the trap 53 rise, is controlled by means of a means 58, and particulates caught and collected by the trap 53 is burned again. At the above device, atomospheric pressure is detected by means of a sensor 59. And the detected value of the trap front and rear pressure difference and the set value of the trap front and rear pressure difference are respectively corrected by means of respective means 60, 61 so that the detected value may become smaller or the set value may become larger as the detected value of atmospheric pressure keeps dropping.
